December 15, 2008 - RF Engineers are primarily concerned with real signal power when sizing components and implementing controls for optimization of signal fi delity and/or data integrity. In communication links, RF signal power is carefully managed to maintain high performance and reliable connections over some distance. Transmitters carefully monitor signal power to maintain high levels of efficiency, and conformity to spectral regulations. Receivers monitor signal power to maintain optimal sensitivity and selectivity.
Most every power detector available on the market has been designed for broadband communications systems. However, it is the manufacturers of test equipment, developers of military and space technology, and advanced physics labs that have challenged companies such as Hittite Microwave Corp. to develop power detector technology best suited for measurement performance in terms of input sensitivity, dynamic range, repeatability, speed and accuracy over temperature.
